Dry cured ham quality as related to lipid quality of raw material and lipid changes during processing: a review.
Gandemer Gilles
Lipids play a key role in sensory traits of dry cured hams. Both the quantity and the composition of lipids in raw material affect dry-cured hams quality. The lipid characteristics strongly depend on rearing systems developed in different area in Europe. During processing, lipids undergo lipolysis and oxidation. Phospholipids are the main substrates of both lipolysis and oxidation. Lipolysis forms free fatty acids rich in polyunsaturated fatty acids all along the process. Lipids are also subjected to oxidation which forms many volatile compounds. These volatiles affect in the aroma of dry-cured hams and are associated with aroma notes such as rancid, aged meat or dry-cured. According to the genotype and the rearing conditions of pigs and the parameters of processing, dry-cured hams have specific sensory profiles. This paper reviews the present knowledge on lipids and dry-cured ham quality.
